We apply latent space cartography — the systematic mapping of structure in pre-trained embedding spaces (Liu et al., 2019) — to three general-purpose text embedding models using Wikidata knowledge graph triples as probes.

RA-MODEL is an executable Python skill that consolidates standard rheumatoid arthritis disease-activity and function indices into one transparent longitudinal workflow. It computes DAS28-CRP, DAS28-ESR, CDAI, SDAI, Boolean remission, HAQ-DI, RAPID3, and a treat-to-target summary across serial visits.

Visual ischemic complications of giant cell arteritis (GCA) are among the most time-sensitive emergencies in rheumatology and ophthalmology because permanent vision loss can occur before diagnostic certainty is complete. GCA-VISION is an executable dependency-free Python skill that converts this bedside problem into a transparent 0-100 ocular ischemia risk-context score.

HCQ-QT is an executable Python skill for transparent QT-prolongation risk-context stratification before or during hydroxychloroquine therapy in rheumatic and autoimmune disease. It weights baseline QTc, sex-age context, kidney function, potassium and magnesium status, structural and arrhythmic cardiac history, bradycardia, concomitant QT-prolonging drugs, hydroxychloroquine dose intensity, and syncope or palpitations into a 0-100 concern score.

Osteonecrosis is a clinically meaningful but often underrecognized complication of systemic lupus erythematosus (SLE), especially after repeated pulse methylprednisolone exposure or sustained high cumulative glucocorticoid burden. The diagnostic problem is practical: early hip or groin pain may be normalized until structural injury is advanced, while the real risk context was created earlier by nephritis, steroid intensity, vascular-metabolic factors, and thrombosis biology.

Gene regulatory networks (GRNs) encode the logic of cellular decision-making, with attractors representing stable cell states and feed-forward loops (FFLs) providing signal processing functions. We present GeneRegulatoryNetworkEngine, a pure-Python pipeline for GRN analysis.

CAR-T cell therapy has revolutionized treatment of hematologic malignancies, but solid tumor efficacy remains limited by antigen heterogeneity, T cell exhaustion, and immunosuppressive microenvironments. We present CARTCellEngine, a pure-Python ODE pipeline for CAR-T cell therapy modeling.

Cytokine signaling through NF-κB and JAK-STAT pathways coordinates immune responses, inflammation, and cell fate decisions. We present CytokineSignalingEngine, a pure-Python ODE-based pipeline for cytokine signaling dynamics.

Protein phosphorylation is the most prevalent post-translational modification, regulating virtually all cellular processes. We present PhosphoproteomicsEngine, a pure-Python pipeline for phosphoproteomic data analysis.

Chromatin accessibility measured by ATAC-seq reveals the regulatory landscape of the genome, identifying active enhancers, promoters, and transcription factor binding sites. We present ChromatinAccessibilityEngine, a pure-Python pipeline for ATAC-seq analysis.

Somatic copy number alterations (SCNAs) are ubiquitous in cancer, driving oncogene amplification and tumor suppressor deletion. We present CopyNumberEngine, a pure-Python pipeline for copy number analysis from whole-genome sequencing.

Protein ubiquitination is a versatile post-translational modification regulating protein degradation, DNA repair, signal transduction, and cell cycle progression. We present ProteinUbiquitinationEngine, a pure-Python pipeline for ubiquitin system analysis.

Neurogenomics integrates genomic, transcriptomic, and epigenomic data to understand brain function and neurological disease. We present NeurogenomicsEngine, a pure-Python pipeline for brain transcriptomics analysis.

Metabolic flux analysis quantifies the flow of metabolites through biochemical reaction networks, enabling prediction of cellular metabolic phenotypes. We present MetabolicFluxEngine, a pure-Python pipeline for constraint-based metabolic modeling.

Tumors evolve through clonal expansion and diversification, generating intratumor heterogeneity that drives treatment resistance. We present ClonalEvolutionEngine, a pure-Python pipeline for tumor clonal evolution analysis from multi-region sequencing.

RNA secondary structure is critical for function, regulating translation, splicing, stability, and protein binding. We present RNAStructureEngine, a pure-Python pipeline for RNA secondary structure prediction and analysis.

MicroRNAs (miRNAs) are ~22 nt small non-coding RNAs that post-transcriptionally regulate gene expression by binding to 3'UTR seed sequences. We present MicroRNAEngine, a pure-Python pipeline for miRNA target prediction and regulatory network analysis.

Ribosome profiling (Ribo-seq) enables genome-wide measurement of translation by sequencing ribosome-protected mRNA fragments. We present RibosomeProfilingEngine, a pure-Python pipeline for Ribo-seq analysis.

Long non-coding RNAs (lncRNAs) regulate gene expression through diverse mechanisms including chromatin remodeling, transcriptional regulation, and post-transcriptional control. We present LncRNAEngine, a pure-Python pipeline for lncRNA regulatory analysis.

Circular RNAs (circRNAs) are covalently closed RNA molecules generated by back-splicing that function as miRNA sponges, protein scaffolds, and translation templates. We present CircularRNAEngine, a pure-Python pipeline for circRNA analysis.
